DRIVING MECHANISM.

Specification of Letters Patent.

Patented Jan. 23, 1917.

To all whom it may concern:

Be it known that I, Vrc'roR IV. PAGFJ, a citizen of the United States,residing at Bristol, county of Hartford, State of Connecticut, haveinvented a certain new and useful Driving Mechanism, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the ac companying drawings, forming part ofthis specification.

Hy invention relates to driving mechanism and more particularly topulleys and the like.

One object of my invention is to provide a pulley or the like capable ofeasy attachment to any of the usual forms of driving shaft and whichwill permit of the running of the engine free of the pulley rim and willalso permit of a speed change between the shaft and the rim.

Another object is to provide a selfcontained pulley 'or the likeembodying a free engine clutch and a speed change gear.

Another object is to provide means for first freeing the clutch and thenthrowing in the speed change gear.

Another ob ect is to provide a mechanism which, while strong andefficient, is simple and easy to assemble and operate.

To. these ends and also to improve generally upon devices of thecharacter indicatedmy invention consists in the following mattershereinafter described and claimed.

In the accompanying dra\vings:-Figure 1 is a longitudinal diametricalsection of one embodiment of my invention substantially on line 11 ofFig. 2; Fig. 2is an end view of the device illustrated in Fig. 1; Fig. 3is a detail of the lost motion connection illustrated in Fig. 2; Fig. 4shows an embodiment of my invention differing somewhat from theembodiment illustrated in Figs. 1, 2 and 3, being a longitudinaldiametrical section on line 4-4 ofv Fig. 5; and Fig. 5 is a sectionsubstantially on line 5-5 of Fig. 4.

Referring more particularly to Figs. 1-3 inclusive, my invention isshown embodied designated generally as 1,

the engine 3 of a motor bicycle or the like. The pulley 1 comprises,generally, a dI'W ing member or sleeve 4 for direct fast connection withand support by the engine shaft 2 and a driven traction member or rim 5for connection with a belt or the like. The rim 5 is rotatably mountedwith respect to the sleeve 4.

Between the sleeve and rim are arranged a direct driving connection andspeed change driving connection. In the present instance the directdriving connection comprises a clutch, designated generally as 6, which,when active, directly connects members 4 and 5 and, when inactive,permits the sleeve and rim to run free of each other thereby to providefor a free engine or for the throwing in of the indirect driving connection.

The speed change driving connection, designated generally as 7, is shownas a planetary transmission of the so-called all spur type comprising adriving gear 8 fast with the sleeve 4, one or more double spur gears 9each having one of its gears, as the larger 10, in mesh with the gear 8and its other gear, as the smaller 11, in mesh with the driven gear 12fast connected to the rim 5. The spur gears 9 are carried upon arotatable carrier 13 which may be held from rotation as by a brake 14.Thus, in the above described mechanism, with the clutch 6 active and thecarrier 13 free to rotate, the

drive is direct and high speedfrom the sleeve 4 through the clutch 6 tothe rim 5; with the clutch inactive and the carrier free the directdriving connection between the sleeve and rim is inactive and the enginefree; with the clutch free and the carrier held from rotation the driveis indirect and slow speed from the gear 8 of the sleeve 4' through thegears 10 and 11 to the gear 12 and thence to the rim 5.

In the illustrated embodiment the sleeve 4 is directly and non-rotatablyconnected to the shaft 2 by being slipped over the tapered end thereofand held thereon by the nut 15 and the key 2*. As here illustrated thesleeve 4 isprovided With an outstanding portion 16 preferably in theform of a flange which for compactness may conveniently be set back tooverhang the projecting bearing of the engine. Upon the flange 16 isshown,- rotatably supported, the before referred to traction member, asthe rim 5.

The rim 5 is provided with a portion 17 which overhangs a part of thesleeve 4 and such portion carries, preferably screwed thereon asindicated at 18, the abutment 19 preferably in the character of a platewhich projects inward toward the sleeve 4. Thus 5 there is providedbetween the rim and the sleeve an oil chamber 20 in which isconveniently received the before referred to clntch 6.

Theelntch 6 is here shown as of the fi'iction disk type and comprises aseries of disks, as 21, slidably and'non-rotatably connected to the rim,as by keying at 22, and a second series of disks, as 23, slidably andnon-rotatably connected to the sleeve 4. This latter connection ispreferably efi'ected by means of the sleeve 24 to which the secondseries of disks is slidably and non-rotatably connected, as by keying at25, and which sleeve is in turn slidably and non-rotatably connected tothe sleeve 4. Preferably the sleeve 24 is connected to sleeve 4 by meansof a series of pins, as 26, projecting into slots, as 2?, in the sleeve4.

The clutch 6 is, preferably, normally and exerting their force againstthe clutch disks to force them towardthe abutment 19. As here shown thesprings are in contact with a flange carried, as integrally, by thesleeve 24. It vfill be seen that the flange 30 and the springs rotatetogether so that there is no friction or wear therebetween. It will alsobe seen that the flange 30 is in effect an additional clutch disk but,being carried with the sleeve 24, s so placed as to be shifted againstthe tension of the springs to relieve the remainder of the disks frompressure when the sleeve 24 is Shifted toward the springs. Any Suitablemeans for positively shiftmg the sleeve 24 may be provided. Inthepresent instance there is provided a means for shifting the pins 26 intheir slots to thereby shift the sleeve 24 Such means may comprise asleeve31 oscillatively mountupon a suitable support, as the axle 32, andprovided with a cent the cam 33, and conveniently mounted upon theaxle32, is arranged a slidable and non-rotatable ring 34 which may beattached to the axle, as by squaring at 35. The connection between thering 34 and the pins 26 is preferably by means of the annulus 36,carried by the pins, and the interposed slidably and rotatably' mountedball-thrust 37. The sleeve 31 may be conveniently oscillated by the arm38 rigidly attached thereto as by squarmg.

It will be seen that, in the above recited construction, when the sleeve31 is oscillated to bring the high portion 39 of the cam 33 into contactwith the corresponding high face cam 33. Adja portion 40 of the ring 34the ring will travel along the axle 3:2 toward the right (as the partsare illustrated in Fig. 1) to thereby force the sleeve 24 toward thesprings 28 and thus release the clutch. Preferably, and as shown, thehigh portions are of considerable extent whereby after the clutch hasbeen relieved further oscillation of the sleeve will have no othereffect than the holding of the clutch released.

It will be seen that the longitudinally shiftable ring 36 has radialclearance with respect to the fastening device, or nut, 15 andthe shaft2. This is conducive to compactness as it permits the end of the shaft,the nut, and the ring to be closely housed in the chamber of the drivingmember 4,'since the ring can overlie the not and the shaft in itsshifting movements.

In the illustrated embodiment the slow speed change drive from thedriving. memher 4 to the rim 5 is effected by the before referred togears 8, 10, 11 and 12 res ectively. The gear 8 may conveniently, and ashere shown, be formed integrally with the inner race member 41 of theantifriction bearing 42 which serves to antifrictionally support thecarrier 13 upon the sleeve 4. In this construction the key 41 for therace member also serves to prevent rotationof the gear on 5 the sleeve4. The double spur gears 9 are shown as mounted upon the carrier 13 bymeans of the spindles 43. The gear 12 is shown as rigidly attached, asby screws 44, to the extension 45 of the abutment 19. In 0 this way theabutment is made to serve not only as an abutment but also as a gearsupport. Preferably the carrier 13 and the spindles 43 are addit'onallysupported by the ring member 46 to which the pins 43 are screwed andwhich is antifrictionally supported upon the extension 45 by theantifriction bearing 47. The inner and outer race members of the bearing47 may be 0011- veniently'provided as integral parts of the; extensionand of the ring respectively. It will be seen that member 19 serves as arace member as well as an abutment and a, gearsupport thus tending tosimplicity and compactness.

In order to provide an oil and protecting chamber for the reception ofthe double spur gears 9, the carrier 13 preferably carries the wallmember 48 which is shown as extending generally parallel to the spindles43 and ba ing an inwardly extending flange 49 in contact with the ring46. The wall member 48 is shown as connected to the carrier 13 by meansof screws 50 and to the ring 46, as by rivets. Evidently the ring 46serves not only as a support but also as a Wall of the gear chamber.

The axle 3:2 is here shown as held against rotation by means of theanchor plate 51 non-rotatably attached to the axle, as by being squaredthereon as indicated at 52, and having its arms supported by the posts53 and 54 respectively, adapted for rigid connection with the engineframe. This latter connection may be effected by foot pieces 53 and 54threaded to the posts and designed for direct attachment to the engine.

The carrier 13 may be held from rotation, in order to throw' in thespeed change drive, by any suitable means. As here shown there isprovided the before referred to brake 14 conveniently mounted forbraking contact with the outer surface of the wall member 48. The brakemay be mounted and operated in any suitable manner. In this way themember 48 serves not only'as a wall of the gear chamber but alsoprovides a braking surface.

In the illustrated embodiment the brake 14, in the character of aflexible band, substantially surrounding the wall member 48, issupported from the collar 55 oscillatively mounted upon the post 53. Thecollar 55 is provided with substantially diametrically opposite arms 56and 57 respectively to which the brake band is connected as by havingone of its ends, as 58, directly pivoted to the lower arm 57 and itsother end. as 59, connected to the upper arm by the T bolt 60 to whichthe brake is pivoted. The T bolt may be adjusted by means of its thumbnut 61 to vary the initial tension of the brake band.

Substantially diametrically opposite the collar 55 the brake band ispreferably guided and held in position by the jawed lug 62 car- ,ried bythe brake band and receiving between its jaws the post 54. Evidentlyupon oscillation of the collar 55 counter-clockwise (as the parts areshown in Fig. 2) the brake band will be drawn against the brakingsurface of the wall member 48 substantially throughout the length of itsperiphery and the braking force will be applied in propor: tion to thedegree of'oscillation.

Preferably there is provided a common means for first releasing theclutch 6 (to render inactive the direct driving connection) and thenapplying the brake to throw in the indirect speed change drivingconnection, and any suitable means may be employed for this purpose. Aconvenlent and preferable means, that here shown, comprises a bell cranklever 63, conveniently carried upon the post 53, and having one of itsarms, as 64, under the control of the operator, as by the link 65pivoted thereto, and having its other arm, as 66, connected, as by thelink 67, to the operating arm 38 of the sleeve 31,, such link beingpivoted at its respective ends to the arms. The bell crank lever isprovided with a contact element. shown as a lug 68, and the collar 55 isprovided with a corresponding lug 69, the two lugs projecting towardeach other andinto a common path but being so spaced circumferentiallythat when the parts are in initial position the lugs are spaced apart asufficient distance to permit of a considerable movement of the bellcrank before they are brought into contact. This space is suflicient toprovide for the release of the clutch before the lugs are brought intocontact. Upon contact of the lugs any further forward movement of thebell crank will cause a corresponding forward movement of the collar 55whereby to apply the brake, the clutch meanwhile being held inactive.Conveniently, and as here shown, the collar 55 is rotatably mounted uponand about the hub of the bell crank, whose arms may be rigidly attachedto its hub in any suitable manner, as brazing, after the assembly of thehub and collar.

The pulley rim 5 may conveniently be provided with a removable facemember .detachably held to the rim proper as by screws 71. Thisarrangement provides for the easy substitution of different pulley facesshould one become worn or one of different construction or contour bedesired. Preferably, and as here shown, the pulley rim is carried uponthe driving member 4 by an antifriction bearing, such for example as thebearing 7 2 of the combined radial and thrust type. Conveniently theflange 16 provides, integrally therewith, the inner race member 73 ofthe bearing 72. The outer race member 74 of the bearing may be held inposition by the ring 75 abutting the shoulder 76 and bythe ring 77threaded to the rim.

The driving member 4 may, if desired. have a. support additional to thatprovided by the shaft 2 as by being-partially supported upon the axle32. as by the combined radial and thrust bearing 78. The inner racemember 79 of this hearing is conveniently provided by the oscillativesleeve 31, resulting in compactness. The outer race member 80 of thebearing may conveniently be held in position by the washer 81 abuttingthe shoulder 82 of the sleeve 4 and by the ring 83 threaded to thesleeve 4. Preferably, and as here shown, the ring 83 abuts with itstapered surface the sleeve 4 and the key 41*, whereby the ring servesnot only to hold the race member 80 in position but also to hold themember 41 and gear 8 in position. If desired a dust cap 83 may becarried by the member 13 as shown.

' In Figs. 4 and 5 there is shown an embodiment of my invention in whichthe indirect drive is effected by a planetary transmission of theso-called internal gear type.

The embodiment of Figs. 4and 5 is essentially similar to that of Figs. 1to 3 being provided with a driving member 84 for attachment to the shaftof the engine, the rim section 85, the releasable clutch 86, and theoscillative cammed sleeve 87 for releasing 3 '10! upon the brake and thethe clutch. The cooperating cams are preferably similar to thosepreviously described. The clutch is maintained active by the spring 88instead of by the plurality of springs 28 of the previously describedembodiment. By the use of the single spring in alinement with the sleeve87 the thrust tending to compress the spring is transmitted in astraight line to the spring. The slow speed drive is effected by meansof planetary gearing the center gear 89 of which is fast connected withthe driving member, the planet gears 90 of which are rotatably connectedwith the rim portion for movement therewith and the outer internal gear91 of which is carried by the shell 92 rotatably mounted with respect tothe driving member and the rim portion. The shell. when it is desired tothrow in the slow speed driving connection. may be held stationary bythe brake 93. In this construction with the clutch 86 active and theshell 92 free to rotate the drive is direct through the clutch; with theclutch released and the shell free to rotate the sleeve 84 and rim 85are free each of the other whereby the engine may run free; and with.the clutch released and the shell held from rotation the drive isindirect. the gear 89 causing the planet gears 90 to rotate upon theiraxes and. since the shell is stationary. to travel on the gear 91carrying with them the rim 85. The planet gears are shown asantifrictionally mounted by bearings 94 upon spindles 95 mounted in anabutment ring 96 carried by the rim as by being connected thereto byscrews 97. The brake 93 for the shell may be of any suitableconstruction. As here shown it is an expansible band arranged within theshell and in position to be expanded into braking con tact with aportion of the inner surface thereof. This band. generally circular incharacter, is carried upon a carrier plate 98 as by being connectedthereto by the springs 99. hese springs are connected at one end to thebrake and at their opposite ends to the shiftable spreader plate 100.The latter, in turn, is mounted upon the carrier plate 98 as by means ofthe pin and slot connection 101. The brake is also connected with thecarrier plate by meansof the jawed lug pin 103 upon the carrier. 1 Thebrake is provided with spaced ends 104 and 105 respectively, preferablysubstantially diametrically opposite the jawed lug. The wedge shapednose portion 1060f the spreader 100 rests between the spaced ends 104and 105. It will be seen that when the spreader is moved upward (as theparts are illustrated in Fig. 5) the ends of the brake band are spreadapart, the jawed lug slides downward on the pin 103 and substantiallythe entire brake is forced into contact with the surface of the shell92. Any suitable means for actuating the spreader 100 may be used.Preferably, and as here shown, the oscillative sleeve 87 carries a cam107 arranged for contact, with its nose, with the nose 108 upon thespreader. Thus when the sleeve is oscillated sufficiently the cam 107shifts the spreader upvard and spreads the band ends.

It will be seen that, in the above recited construction the springs 99serve not only to yieldingly support the brake and assist to hold itcontracted with its ends in connection with the spreader but also exerttheir force to hold the nose portion 108 in contact with the cam 107.

The cam 107 is preferably s0 located upon the sleeve 87 that its nosewill not act to shift the spreader untilafter the clutch has beenreleased and the higher portions of the sleeve-shifting cams are inposition to travel upon each other with no other elfect than the holdingof the clutch released. Provision is thus made for the releasing of theclutch prior to the throwing in of the slow speed driving connection.

The carrier plate may be non-rotatably supported as by the arm 109adapted for fast attachment to the engine frame. If desired the spacedends 104 and 105 may be provided with antifriction rollers 110. Theshell 92 may conveniently be supported upon the sleeve 84 by means ofthe radial and thrust antifriction bearing 111 having its inner race 112formed upon the sleeve and its outer race 113 formed upon an inwardlyprojecting partition 114 of the shell.

The sleeve 84 may be supported by the radial and thrust antifrictionbearing 115 having its inner race 116 provided by the oscillative sleeve87 and its outer race 117 connected to the sleeve 84 by being threadedthereto, as indicated at 118, and by the check nut 119. The rim 85 maybe antifrictionally mounted upon the sleeve 84 as by means of thecombined radial and thrust bearing 120 having its inner race member 121abutting a shoulder 122 and its outer race member 123 abutting ashoulder 124. Both race members may be held in place by a ring 125.

The cam 107 is fixed upon the oscillative sleeve by means of a key 126.The sleeve may be oscillated by means of the arm 127 rigidly attachedthereto as by the key 126. The cam and lever are shown as spaced apartby the spacer 128 to which the lever and cam are connected by the pins129.

Movement of the oscillative sleeve 87 longitudinally of the axle 130upon which it is mounted may be prevented by the shouldered portion 131of the axle and by the central portion 132 of the anchor plate 133. Theanchor plate is shown as keyed to the axle at 134 and rigidly connectedto the arm 109 as indicated.

It will be seen that I have provided a device such as a pulley,'whichwill permit of the drive shaft running free; which provides a pluralityof speeds, in which neither driving connection can be thrown in whilethe other is active and which withal is easily attachable to any of theusual forms of drive shaft, and is simple and comparatively inexpensive,and also one in which the traction member, and the two drives aresupported and held assembled upon a single member, as the drivingmember, which may be detachably and easily connected to the drivingshaft.
